Hi. Recently we finished up swapping a GSXR inverted front on to a 75 GL1000 and felt I needed to share this with the community. There was a lot of trial and error before we got it all sorted.
The donor bike was an 06 GSXR 600. The forks were completely rebuilt and heavier weight springs were out in to match the bikes weight along with the rider.
We initially wanted to stay with the wheels that came with the bike (Lesters) which were worlds lighter than the stock spoke wheels. Upon the initial attempt to fit the wheel we discovered the rotors sat too far out and actually didn't fit between the forks. We didn't spend much time trying to sort this issue. Maybe later down the road we will dabble with it again. Instead we went with the Suzuki wheel.
Ok, on to the content regarding the forks. The only real modification was completed to the lower triple tree. Essentially the stem is short by about a half inch. Creativity took place and I devised a solution to resolve it.
Tools used:
Manual mill
Lathe
Press
First I pressed out the stem from the tree. Be gingerly with this or you can snap the lower tree mount.
Next I threw the lower tree on the lathe and machined out the lower ID stop flange. Roughly 3mm. This will allow the stem to actually press in further. The lower stem flange sits just outside the tree in stock form. Now the flange sits flush to the bottom of the tree.
After that simply throw the lower tree on the mill and deck roughly another 3mm off the top as shown in the photo.
Next it's time to press the stem back in. Use caution when pressing it back in. You don't want that dude going in crooked.
Once that is finished bolt it all up and rule the world. We used the recommended Allballs bearing kit for those curious. These modifications allow the stem to come out enough to allow the upper tree to bolt on.
There's still work needed before we get the bike out on the road but it's making progress and really looks awesome. Hopefully it performs equally as good. Let me know if there are any questions. I'll answer what I can.
